Well, Good to see you back, and that things are improving. Catching up on replies? Yup, that ought to keep you busy for a short while at the least. ;-)
Hurrah! I got an email notice of your addition to the thread.
While working on the house I thought of something that might be useful in some situations for the people on this thread ... 3M All Weather Flashing Tape 8067.
It ain't purty because it covered with brand markings and code citations so building GC's and inspectors can see what was used. (Most motorhome sealants are designed to look pretty from the outside.)
That said, it appears to be the best possibility for sealing leaks. It sticks to everything, is very flexible, and is puncture resistant.
It's a PITA to work with ... it grabs everything it can and doesn't like to let go. (Removing it to make permanent repairs will probably take a bit of work.) It gums up scissors and tries to stick to razor knife blades. If you have touch the sticky side, do so lightly. If you grasp it firmly, you're going to have a tussle getting it loose from your fingers.
So far, I've tested it on old wood, concrete block, polyethylene, and tar paper. I've decided it's better than the red construction seaming tape (3M 8087 and others). It is possible to get it loose from wood and concrete but only if you really want it to come off. It won't come off polyethylene without tearing the plastic. (Haven't tried removing it from tar paper yet.)
I haven't tested it through an 80 above to 40 below zero cycle yet but am confident it will stand up to those extremes. (In interior Alaska, everybody starts moaning and groaning about how hot it is if the temperature goes above 75°F.)
The red tape should only be used on house wrap and vapor retarder/barrier. Otherwise, it's not much better than duct tape anywhere else.
Yes, I have a very low opinion of duct tape. I usually only have one roll around and the adhesive tends to dry out and lose it's "sticky" long before I get around to using it. (For me, masking tape works just as well or better.)
Even the so-called "hundred-mile-an-hour" tape should only be used for temporary situations, with emphasis on temporary.
On the other hand, a person with a bit of boatbuilding experience could make a serviceable boat using cardboard and the 8067 tape and expect it to last several years.
